VEHICLE AXLB. No. 362,486. Patented May 1'0, 1887.

To @ZZ whom, it may] concern.'

Be it known that I, JOHN M. BEosrUs, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented a new and useful Vehicle-Axle; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and toletters or figures of reference marked thereon, which form a part of this specification.

rlhis invention relates to vehicle-axles, the object being to make them lighter andstronger, as well as more easily renewed when worn, andat the sam'e time to make them easily adj ustable. y

The axle, as improved, consists of a hollow rectangular axle-tree made of metal, of spindles, means of fastening these spindles into the rectangular tubular axle-tree, metal spindlecasing with means of fastening it to the spindle and keeping it from turning, and an axlebox so formed asto exclude dust and any other foreign matter from the wearing parts.

In the accompanying drawings, Figure 1 is a side view, mostly in section, showing the axle-box, spindle, spindle-sleeve, means of fastening the spindle into the tubular axle-tree, and contiguous parts. Fig. 2 is a side elevation showing the axle-spindle fitted ready to receivethesleeve. Thespindleisshownin Figsl and 2 as being somewhat drawn ont and capable of adjustment in the direction of narrowing the track. Fig. 3 is a cross-section online 1, Fig. 1. Fig.4is a section on line 2, Fig. 2. Fig. 5 is a perspective view of the spindlesleeve, showing the notches for keeping it from turning on the spindle.

In the gures, like reference-marks referring to like partsin the several views, the details of constructionare as follows:

, The axle-tree A is made of metal, and is rectangular in form. In it are holes for the'insertion of the set-screws F, which are for the purpose of fastenin g the spindleB in place. The spindle B is made at one end 4to suit in shape and sizethe inside of the axle-tree A, as shown, 5o and at the other end is round and tapering for the reception of the spindle-sleeve C. The

, it from. turning on the spindle.

Y SPECIFICATION forming part of Letters Patent No. 362,486, dated May 10, 1887. Application filed March 15, 1887. Serial No. 231,037. (No model.)

shoulder on the spindle, against which the invner end of the sleeve rests, is a concave fillet, on which is the lng I for thepurpose of entering one of the notches I in the sleeveG tohold 'Ihis sleeve C is made of a taper to correspond on the outside to the inside taper of the axle-box D, and on the inside to the taper of the spindle. The lug I is not necessarily on but one side of the spindle; but the sleeve G has two notches I,in order that the sleeve may be turned half over when worn on the bottom side,'thus presenting a new wearing-surface, which is a great advantage, as it is impossible to entirely stop the wear, even with the best and most approved anti-friction bearings. rIhis sleeve G, I make to overhang the outer end of the spindle, in order that the nut Nwill forc'e the sleeve firmly onthe tapering part of the spindle andhold it in that position.

The axle-box D is made of any required form on the outside, and on the inside, for the greater part of its length, it'is made tapering, to conform to the outside taper of the sleeve C. For the remainder of its length it is made straight or very slightly tapering, and corresponds to the large part i and i of the spindle and the sleeve, respectively, for the purpose of making a long bearing for the exclusion of dust or foreign matter of any description.

For convenience in attaching the other part-s of the vehicle, I place the extra bed J, which is made of wood, on the top of the axle-tree, and hold it in that position by the clips G'. On the ends of the clips G, I place the straps H, which I also utilize for the insertion of the screws F. The screws F are kept from working out by the jam-nutsf. The screws F will hold the spindles firmly in the hollow axle-tree after the width of `track shall have been adjusted, and prevent longitudinal movement of these spindles.

The sleeve C may be attached to any form or size of axle by merely fitting the spindle taper and inserting the lugs I, which would be a saving, as, instead of obtaining new axles complete, all that would be necessary would be to turn the sleeve C or replace the old sleeve by a new one.y

I am aware that extensible axles are old, and that a sleeve covering the spindle or wheel IOO bearinr of an axle is also old. Ido not,there fore, broadly claim either of these devices.

Having thus described my invention, what I cla-im as new, and desire to secure by Letters 5 Patent of the United States, is-

1. In a vehicleaXle, the combination of the rectangular hollow axle A, extension-spindle B, bed J, and clips G, with screw F, arranged to hold both the spindle and bed to the hollow zo body and allow the longitudinal adjustment of the spindles in said body, substantially as set forth.

2. In a vehieleaxlc, the combination of the J. M. BROSIUS.
